Survey Techniques
We are all familiar with the notion that global biodiversity is at increasing risk of extinction due to a variety of reasons. These reasons include, but are not limited to; habitat destruction and degradation, environmental pollution, over-harvesting of wildlife for human consumption, wildlife diseases and climate change. But how do we know that biodiversity is threatened on a global scale? In order to understand fully what is happening to global biodiversity, we must find sensible ways of monitoring it. How we go about this enormous task depends very much firstly on at what level we are trying to assess biodiversity. It is impossible to look at all biological diversity at the same time so we must break it down into more manageable sections in some way.
